ANTIFRICTION HUB OR WHEEL BEARING.

SPECIFICATION forming part Of Letters Patent No. 586,535, dated July 13,1897.

Application filed May 1'7, 1897. Serial No. 636,880. (No model.)

To all whom it may concern: hub, the case, and its rolls rotate aboutit, as Be it known that 1, JOHN H. VINTON, of would happen, say, if thebearing-hub is in a Boston, county of Suffolk, State ofMassachupulley-block or in a trolley-wheel.

This expansible ring may, if desired, be made with an externaldiameter substantially equal to the inner diameter of the case or ring,and when the said ring is cut into segments it may be expandedoutwardly; or I may, if desired, use a ring composed of spring-wire,shaped substantially as in Fig. 7, so that it may be contracted to enterthe open end of the solid case or ring and thereafter expand, said ringentering both the annular groove a and the grooves of the rolls.\Vhenever this eXpansible ring, of Whatever form, is made to engage thegrooves in the rolls and the annular groove in the solid case or ring,the said expansible ring will act to lock and hold the rolls inposition.

Believing myself to be the first to use an expansible ring in the mannerherein described, this invention is not limited to the particular shapeor construction of the ring, so long as it has the capacity of beingcontracted to enter with the rolls into the interior of the case, andmay thereafter be expanded, so that the said expansible ring maypartially enter the groove a at the interior of the said case.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. A hub-bearing, composed of a solid case or ring-like shell, providedat its interior with an annular groove, a nest of rolls, a bearingringnotched exteriorly to receive the jour-' nals of said rolls, and anexpansible loose ring adapted to enter both the annular grooves of therolls and the groove at the inner side of the said solid case orring-like shell, substantially as described.

2. A hub-bearing, composed of a solid case or ring-like shell, providedat its interior with an annular groove, a nest of rolls, a bearingringnotched exteriorly to receive the journals of said rolls, and anexpansible loose ring presenting segments and adapted to enter both theannular grooves of the rolls and the groove at the inner side of thesaid solid case or ring-like shell, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN H. VINTON.
